| Title: | Open mappings increasing order |
| Authors: | Charatonik, JJ

| Issue Date: | 1997 |
| Abstract: | It is shown that an analog of Whyburn's theorem saying that open mappings do not increase order of a point of locally compact metric spaces is not true if the Menger-Urysohn order is replaced by order in the classical sense. On the other hand, this analog is true, even for a wider class of confluent mappings, under an additional condition that the mapping is light and the domain continuum is hereditarily unicoherent. |
